In traditional web application development user sends the request on server

to the browser. Browser then displays the content to user. In case of Ajax
complete page refresh is not required to change a part of the web page. Ajax
sends the asynchronous request to the server for retrieving small piece of data
and waits for the server response. After receiving the response from the server
JavaScript part of the Ajax display the data on the web page.

date and time of the server.
